I have a graph that no longer works in R2025 due to unrecognizable user created node. If I update the node to the current version, does it stand a chance of it not working in R2023, 24?
Once the new collection of nodes are installed there is no way to keep old installation and new installation separate, right?
Thanks,

It stands a chance, sure - anything is possible.
However if one of the API calls changed between 2023 and 2026 then you’ll have to have separate versions of the node or a ‘switch’ in the code to execute only the correct version.
So if the previous node took a Dynamo point, pulled it onto a plane, and then converted it to a Revit XYZ you’ll likely be all set in 2023, 2024, 2025, 2026, and even 2027.
But if the previous node took an integer, converted to an element ID, got a toposurface, Extracted the faces, and built a Dynamo mesh, you’re going to need a different build in 2023 (base), 2024 (element ID changes), 2025 (toposurface change from 2023), 2026 (toposurfaces removed entirely), and 2027 (mesh tool changes).
Likely you’re somewhere in between - most are.
How the node was built and what it does is the most important bit.
